I'm building an animation where an object starts as wireframe, then transforms to solid. Blender 2.79b, Cycles.
I have two duplicates of the object, one of which has a wireframe modifier applied. Then I use an object (a cylinder for now) as a boolean object, set to Difference on the wireframe copy and Intersect on the solid copy. The boolean object has its Camera setting turned off in Cycles Settings. By animating the shape, position and scale of the boolean object, I can achieve what I'm looking for.
However, it would be cool to add a glow effect at the boundary, as if there's electric, transformative energy, say. I can't think of a way to do this. Any ideas?
Thanks!
